First, the primary information (voice) channel loop back test is run. The test is
performed by sending a digital count from the Tone-Clock circuit pack on the
primary information channel time slot and receiving the same digital count with a
general purpose Tone Detector.
While the primary information channel is still looped around, the Control Channel
Loop Around Test is performed. This test consists of sending four different
transparent patterns to the on-board microprocessor, receiving them back, and
comparing them.
The Loop Around Test for the secondary information (data) channel is then
performed. This test is the same as the primary information channel loop around
test and is performed only if a DTDM is administered.
A Conference Test is done next for the primary information channel. This test is
the same as Conference Test #6.
Only one value (Pass, Fail, or Abort) is generated as a result of four tests run. If
any test fails or aborts, the sequence is stopped.

ABORT Internal System Error
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to abort, escalate the problem.
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call. Use display port PCSSpp to determine the
station extension or attendant number of the port. Use status station or
status attendant to determine the service state of the port. If the service
state indicates that the port is in use, then the port is unavailable for certain
tests. (See Chapter 10, "Maintenance Commands and Trouble-Clearing
Aids", for a full description of all possible states.) You must wait until the
port is idle before retesting. Attendants are always in use (off-hook) if the
handset is plugged in and the port is not busied out.
1. If the port status is idle, then retry the command at 1-minute intervals a
maximum of 5 times.
2. If the test continues to abort, escalate the problem.
1001 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If the test continues to abort, escalate the problem.
